Data Science vs Big Data vs Data Analytics – Understanding the Terms
As per Gartner, “Big data is high-volume, and high-velocity and/or high-variety information assets that demand cost-effective, innovative forms of information processing that enable enhanced insight, decision making, and process automation”.
Big Data implies an enormous volume of raw data which a usual application such as a Traditional Database Management System can’t process efficiently. Due to its high volume, the applications can’t store the data within a single computer’s memory. This amount of structured and unstructured data (big data) overwhelms businesses on a regular basis. This data needs to be utilized to analyze business insights in order to take strategic business moves and better decisions.
Data Science involves the processing of big data (both structured and unstructured) including the preparation, analysis, cleansing of the data. It also involves programming, mathematics, statistics, problem-solving, capability to view things differently, intuitively capturing data etc. You can say that data science is a broader term for the techniques involved in retrieving insights and information from the data.
The science of raw data used to derive meaningful information and conclusions from that existing data is known as data analytics. It constitutes of implementing a mechanical or algorithmic process for extracting insights from existing raw data.
Numerous industries utilize this process to enable them to take effective decisions along with verification and disprove old models or theories. Data analytics tools help you speculate the outcomes, depending upon the facts known to the researchers.
After understanding data science, data analytics, and big data, it is obvious that they are dealing with the same thing – ‘data’. As it’s essential to work on a huge volume of data, data analytics broadly encompasses the involved processes herein. So, what’s analytics in the simplest of forms? It is nothing but the process of understanding and devising effective patterns for recorded data using mathematics, statistics, machine learning techniques, and predictive modelling.
In the next section, we’ll proceed towards Data Science Vs Big Data Vs Data Analytics considering various factors.

Data Science Vs Big Data Vs Data Analytics: Tools & Technologies
Speaking of data analytics tools you can learn any desired analytics tool that suits your specific goal. The most popular analytics tools are SAS, Python, R, Hadoop, Clickview, Tableau, Microsystems etc. Considering data science vs big data vs data analytics, followings are the tools and technologies related to these terms.
Big Data Tools
Hadoop is a Java-based open-source framework responsible for running applications and storing data over clusters of commodity hardware. It also allows expansive storage of the varied range of data, enables handling virtually unlimited concurrent jobs/tasks. It is basically focused to manage financial, operational, and constitutional – big data. Hadoop is one of the most popular, open source big data tools that are highly scalable, has the flexibility to store big data, computes faster, and has the high tolerance against hardware malfunctions to protect data.
NoSQL is one the most important Big Data tools, it is used for handling unstructured data as the traditional SQL is used to handle the structured data. The application and scope differentiate NoSQL from SQL, to understand it better read the article on NoSQL vs SQL. NoSQL doesn’t use any particular schema in order to store unstructured data. There are common values in each set of rows. If you want to store a large amount of data, in that case, NoSQL works very effectively. Also, for the analysis of data, there are a number of open source NoSQL databases.
Apache Hive is the distributed data management tool for Hadoop. Hive has its own query language, that is much similar to the SQL. The query language of Hive is HiveSQL, generally known as HSQL. Hive Query Language runs on the top of the Hadoop architecture, it is mainly used for the data mining and data management.
Data Analytics Tools/Languages
It is an open source programming language as well as a software environment that facilitates graphics and statistical computing. It is vastly utilized by data miners and statisticians in order to develop statistical software and data analysis. R is broadly used in social media sites, manufacturing, predictive modeling for automotive, data visualization in journalism, finance and banking, drug and food manufacturing, and generating reports in big data. R is mostly used for representing visual data or you can say it is a visual data analytics tool.
Tableau Public is an open source data analytics tool that is used to connect data source and creates dashboards, visualizations, maps, etc. with the real-time updates presented on the web. Such data insights created with Tableau can be shared with the client via social media or any other mean. It is found to be the one of the best software used for the visualization and analysis of data when compared to the other data visualization and analysis software available in the market.
Apache Spark is a data processing engine that can execute applications in Hadoop clusters at a very speed. The execution speed of Spark is 100 times faster in memory and 10 times faster on disk. Spark is very popular for the development of machine learning models and data pipelines. Also, it makes data analysis an effortless process. MLlib, the Spark Library, provides a number of machine algorithms for repetitive data science techniques.
Data Science Tools/Languages
SAS is a software suite, primarily used for data management, business intelligence, advanced analytics, predictive analytics, and multivariate analysis. It has two models to suit the developer community, for people who love programming – Base SAS or Miner, and who are not fond of programming – Visual Analytics.
Python is an open-source interpreted, object-oriented, high-level programming language with dynamic semantics. It’s capable of Rapid Application Development and works as a scripting language to connect existing components together, because of the high-level built-in data structures, dynamic binding, and dynamic typing. Broadly being used for finance, automotive, and manufacturing, this tool allows data munging and creates web-based analytics products.
Python and R both are the data analysis tools used by the data scientists. If you are confused to choose between Python and R, you can read our previous blog on Python or R – which one should you learn?
SQL is one of the most favorite languages of data scientists. SQL is a traditional language that has been used to store and retrieve data for decades and still being used. SQL is mainly used to handle large databases with huge data. Its fast processing time helps to reduce the turnaround time for online requests. If you want to build a career in data science or machine learning, then learning SQL will be an add-on to your skills.
